Ready for transition.

In designing the Men's Free Tri Shorts, Castelli clearly considered all three disciplines in equal proportions to successfully navigate a multisport event. With functionality for each distinct leg of the race, these shorts transition seamlessly from one discipline to the next.

The Free Tri Shorts are constructed with Castelli's hydrophobic Instadry Speed fabric. This material's tight knit composition holds your muscles comfortably in place, providing needed protection from run impact and road vibration. A notable perk to the next-to-skin fit is that the shorts won't cause any excess drag, both on the land and in the water. And in terms of the latter, Instadry's hydrophobic treatment provides a smooth surface that cuts through the water. Additionally, this material prevents water absorption from weighing you down during your swim and causing discomfort after T1.

The panels are joined with flatlock stitching throughout, preventing chafing and irritation during your run or ride. Castelli's GIRO3 leg gripper system and draw cord waist comfortably hold the Free Tri shorts perfectly in place throughout the versatile movements of your race.

The Free Tri Shorts incorporate Castelli's triathlon-specific KISS Tri chamois, designed to work most effectively while you're in the aerodynamic position on the bike, with unnecessary foam trimmed away to optimize comfort during the run and swim portions of your race. Furthering this concept, the surface of the insert is entirely free from seams. And when mated with the chamois' engineered elasticity and low, 3mm density, Castelli guarantees that it'll follow your locomotion during the run.

Thin but comfy

These shorts are excellent. They stay right where you want them to and the chamois is very thin, but still offers a lot of comfort. They fit pretty tight, but are designed just right for their tight fit.

Oceanside 70.3

Familiarity: I've used it several times

Fit: True to size

Size Bought: xxl

I purchased these for the Ironman Oceanside 70.3 and they were great. The chamois is course thinner than a road chamois but it was comfortable and did the job as expected. The fit was good and the shorts have pockets for nutrition and the sorts.
